摘要: 岔路河组原称砂砾岩段,分布于伊通至舒兰地区.山灰绿色泥岩与杂色砂砾岩组成,厚200~500m.本组含丰富的孢粉化石,以两气囊松科和草本植物花粉含量高为特征,确立其地质时代为中新世晚期.建组剖面为万参1井,井段为32.0~288.5m.本组与上覆第四系呈角度不整合接触,与下伏下第三系万昌组呈平行不整合接触.

Abstract: Chaluhe formation previously called as"Sand conglomerate member"distributes in the area from Yitong to Shulan.It consists of grey greenish mudstone and varicoloured sandy conglomerate,with a thickness of 200 to 500m.The formation contains prolific sporo-pollen fossils,characterized by high contents of Pinaceae of Bisaccatepollen and herbaceous.The Epoch is determinde to be late Miocene.It's typical profile is observed in an interval from 32.0 to 288.5m in the well of Wancan l,Where an unconformity exists between this forma-tion and the overburden Quaternary and a disconformity exists between this formation and the underlying Palaeogene Wancang formation.
